Replace the hardcoded tls.VersionTLS13 in the activator's HTTPS server with the shared knative.dev/pkg/tls package, allowing TLS settings to be configured via ACTIVATOR_TLS_MIN_VERSION, ACTIVATOR_TLS_MAX_VERSION, ACTIVATOR_TLS_CIPHER_SUITES, and ACTIVATOR_TLS_CURVE_PREFERENCES environment variables. The default remains TLS 1.3 when no env var is set. Signed-off-by: Mikhail Fedosin <mfedosin@redhat.com>
